The FIG 7003 Hingelok Coupling is specially designed for applications requiring a quick connection and/or disconnection of a pipe joint. The hingelok coupling is ideal for those applications where frequent pipe removal is required for maintenance or any other reason. It provides for system working pressure ratings up to 300 psi (20.7 bar). The coupling halves are permanently hinged to provide an assembly that eases handling & installation and are secured by a cam-action handle. Sizes 1" to 4" use toggle link plates and sizes 5" to 8" use a toggle bolt to attach the cam-action handle to the housings. The cam-action locking handle permits rapid installation without the need for additional tools and maintains secure closure of the coupling into the pipe grooves. Final assembly of the locking pin to the hingelok coupling adds an extra measure of security required in critical pipe joint applications. Recommended for petroleum applications. air with oil vapors and vegetable and mineral oils. NOT FOR USE IN HOT WATER OR HOT AIR.
